Sacubitril/Valsartan for heart failure: A protocol for systematic review and meta-analysis

BACKGROUND: Sacubitril–valsartan has been shown to have superior effects over angiotensin-converting enzyme inhibitors and angiotensin receptor blockers in patients with heart failure (HF). However, the effects of sacubitril–valsartan have never been systematically evaluated. Therefore, we performed a protocol for systematic review and meta-analysis to evaluate the efficacy and safety of sacubitril–valsartan in patients with HF. METHODS: We selected 8 databases, including PubMed, the Web of Science, Embase, Cochrane Library, the Chinese National Knowledge Infrastructure, the Chinese Science Journal Database, Wanfang Data, and the Chinese Biomedical Literature Database. The search time was from database establishment to March 2022. Two reviewers will screen the records and include quality studies according to inclusion criteria independently. Two reviewers will assess the risk of bias of the included studies by the “Risk of Bias Assessment Tool” of the Cochrane Handbook for randomized controlled trials. Statistical analysis will be performed with Review Manager software 5.3. RESULTS: A synthesis of current evidence of sacubitril–valsartan for treating HF will be provided in this protocol. CONCLUSION: The results of this study will provide a theoretical basis for the clinical use of sacubitril–valsartan to treat HF.
